Abstract

Grapholita molesta (GM) has been considered as a major problem to apple and peach orchards. Mating disrupters have been applied to control the pest over the world as an Integrated Pest Management [IPM] tool. Various types of dispensers releasing mating disrupters have been developed with different formulation of wax, polyethylene tube and aerosol. In this study, the dispensers that were composed of ester waxes and polypropylene (PP) film were used as dispenser materials to analyze release pattern of GM pheromone compared with paraffin wax and polyethylene (PE) film. The release pattern in PP film group was consistent with time while PE film group irregular. Based on these results, Japan wax_PP film dispenser (Japan_PP) was manufactured and showed the mating disruption effect of 98% during 5months in peach orchard.

복숭아순나방(Grapholita molesta)은 핵과류과실에 일차 피해를 주는 해충이다. 이를 해결하기 위해 종합적병해충관리 [IPM]의 일환으로써 전세계적으로 교미교란제가 농가에 적용되고 있다. 왁스, 폴리에틸렌 튜브, 에어로졸 형태의 다양한 교미교란제가 상업화되었다. 이 연구에서는 복숭아순나방 성페로몬 방출기로써 에스테르왁스와 폴리프로필렌(PP)필름백을 구성하는 방출기를 기존의 파라핀 왁스와 폴리에틸렌(PE) 재질의 필름과 비교하여 페로몬의 방출거동을 분석했다. PE재질의 필름백은 성페로몬의 방출이 불규칙한 반면, PP필름백에서 성페로몬은 시간에 따라 일정하게 방출하는 패턴을 얻었다. 이러한 결과를 토대로 Japan 왁스_PP 필름 방출기(Japan_PP)를 제작하였고, 약 5개월 동안 복숭아과수원에 적용한 결과 98% 이상의 교미교란 효과가 검증되었다.
